TECAFORM® AD EF natural

POM-H Bio-based

REQUEST FURTHER PROCESSING OPTIONS

TECAFORM AD EF natural is a mass-balanced bioplastic based on POM-H (homopolymer acetal) and forms part of our range of products made from bio-based raw materials. Compared with the fossil-based variant, this biopolymer has a lower product carbon footprint whilst offering impressive physical properties such as outstanding sliding characteristics and good wear resistance.

Furthermore, TECAFORM AD EF natural offers a slightly higher density, hardness and strength compared to POM-C. In addition, the bio-acetal homopolymer is characterised by excellent electrical insulation properties and is easy to process. Consequently, this bio-based plastic is ideal for applications in power transmission – for example, in gearboxes for electric motors – as well as in food processing and a wide range of other industries.
As a bio-POM homopolymer from Ensinger, TECAFORM AD EF natural is available in the form of plates and rods.

The material forms part of Ensinger’s ‘Reuse for Tomorrow’ solutions. These comprise carefully developed products which, thanks to a lower PCF compared with their respective fossil-based equivalents, can help to reduce greenhouse gas emissions. The relevant PCF values and information on how they are calculated can be found in the download section.
